I am currently working on a training video with video test patterns. The producers I am working with said that if working in a component video wired system, the Colour control should set all the bars correctly, and only if one is using a Composite or S-video input, the colours may not be displayed properly and need to be adjusted. Is this true? Where can I find information on the web to clarify this?
Follow Ups:
The Color control will adjust the colors equally in all of the systems that you mentioned, but if they aren't in the correct proportion in the first place they won't be corrected by the Color control. That's why displays not only need to be calibrated, they need to be calibrated to the source they are being fed.Here's the short, non-technical, non-exception version. The color you see a display output is a mix of Red, Green and Blue (RGB). If the manufacturer set Red a bit high and Green a bit low, these two colors will still be a bit hot and a bit cool when you adjust the Color control. Think of the Color control as a Master Volume Control in a multi-channel receiver/processor. Turn it up, all channels increase in volume. Turn it down, all channels decrease in volume. If your Center channel was set 2dB too high relative to the other channels, it will still be 2dB too high no matter where the Master Volume Control is positioned.
What is not supposed to be adjusted is Tint/Hue in a component system. That doesn't mean that some displays don't offer this ability. And it also doesn't mean that they are correct in allowing it.
I found this to be an excellent analogy and the best explanation of the situation I have read. Thanks.
Does component video wired TVs automatically disable the Tint/Hue controls where previously available with composite video connections?
I believe that Tint/Hue has something to do with phase. In a component based system, either this aspect of the picture is not necessary or somehow the signals cancel out. I don't remember too much about this, so it might be better to do a search and/or check out some of the technical video forums.This won't help much, but go to "Calibration is Equally Important" from the Video Essentials website in the link below:
